Working as expected (or: working as designed). The behavior with regard 
to inheritance was an explicit section (with its own headline) in the 
RFC and thus was voted and agreed-on. Changing that would be a 
non-trivial change from the agreed-on behavior and thus warrants another 
vote at the very least. The same is true for reverting the readonly 
class feature entirely, especially since PHP 8.2 is in the RC phase 
where it's not entirely unreasonable for users to start building on the 
anticipated features.

FWIW personally I would've preferred avoiding this problem by 
disallowing readonly classes to appear within inheritance hierarchies 
entirely.
